Description

[Detailed Description of the Invention] This invention relates to an emergency stop centering device used when installing an elevator.

Generally, when installing an elevator car, the emergency stop frame that serves as its foundation must first be fixed in the hoistway. This fixing work is performed using an emergency stop device. This will be explained with reference to FIGS. 1 and 2.

In Figure 1, 1 is an elevator car, 2 is an emergency stop frame that supports the car 1, and 3 is an emergency stop frame 2.
This is an emergency stop device housed in the emergency stop device, and the emergency stop frame 2 and the emergency stop device 3 constitute the emergency stop.
In the emergency stop device 3, when the elevator speed of the car 1 reaches an abnormal speed that exceeds the rated speed, a speed governor (not shown) detects the abnormal speed, and the emergency stop device 3 detects the abnormal speed through a speed governor rope (not shown). Pull up the brake 3a,
These brakes 3a are configured to clamp guide rails 4 erected on both sides of the car 1 to bring the car 1 to a sudden stop. Further, reference numeral 5 denotes a mounting member fixed to the emergency stop frame 2 and extending upward;
7 is the car frame fastened to the mounting member 5, and 7 is the car frame 6.
This is the main rope for suspending. The car 1 is guided by the guide rails 4 by the main ropes 7 and moves up and down.

In FIG. 2, reference numeral 8 denotes a pull-up lever equipped with a pin 9 connected to the governor rope (not shown);
A main shaft 10 passes through the emergency stop frame 2 and has a pull-up lever 8 fixed to one end and an operating lever 11 fixed to the other end, and 12 is connected to the tip of the operating lever 11 provided on the brake 3a. The pin 13 shown in FIG. 1 is a rope with one end connected to a suitable position in the hoistway and the other end connected to pin 9, and this rope 13 is used only during installation.

The elevator installation work begins by erecting a pair of left and right guide rails 4 on the hoistway, then transporting the emergency stop frame 2 equipped with the emergency stop device 3 between the guide rails 4, The brake 3a of the emergency stop device 3 is opposed to the guide rail 4. At this time, the installation rope 13 is connected to the hoistway. Thereafter, when the emergency stop frame 2 is moved downward while being held horizontally while maintaining a specified dimension with the guide rail 4, the pull-up lever 8 is pulled by the rope 13 and rotated. As a result, the brake 3a is pulled up and clamps the guide rail 4, so that the emergency stop frame 2 is fixed to the guide rail 4. The car 1 is assembled based on the emergency stop frame 2 fixed in this way.

However, during the above-mentioned elevator installation work, it is difficult to set the position of the emergency stop device 3 with respect to the guide rail 4, and in order to keep it within the allowable value, it usually requires several operations such as moving the above-mentioned emergency stop frame 2 downward. There was a problem that it had to be repeated several times and the installation work was poor.

This invention is an attempt to solve the above-mentioned problem, and by removably fixing the positioning plate that comes into contact with the inner end surface of one of the left and right guide rails to the emergency stop frame with screws, It is an object of the present invention to provide an emergency stop centering device for an elevator that allows easy positioning of the stop.

An embodiment of this invention will be described below with reference to FIG. In FIG. 3, 2 is an emergency stop frame, 3 is an emergency stop device, 4 is a guide rail, and 5 is a mounting member. In addition, 14 is a backing plate for position setting, 15
is a screw for removably fixing the backing plate 14 to the emergency stop frame 2. The abutment plate 14 is attached only to one end of the left and right ends of the emergency stop frame 2, and when the abutment plate 14 is brought into contact with the inner end surface of the guide rail 4, the dimensional relationship between the guide rail 4 and the emergency stop frame 2 is changed. , in particular, are positioned so that the dimensional relationship in the left and right direction is properly set.

Therefore, by bringing the backing plate 14 into contact with the guide rail 4, the dimensions of the emergency stop frame 2 and the guide rail 4 are set, so the emergency stop frame 2 is fixed to the guide rail 4 using the aforementioned work procedure. If so, centering for these will be performed automatically.
After fixing the emergency stop frame 2 in this manner, the backing plate 14 is removed and the car frame 6 is assembled, thereby making it possible to easily and accurately center the emergency stop. It should be noted that in this embodiment, other than the above-mentioned parts are the same as those shown in FIGS. 1 and 2 and described above, so the explanation will be omitted.

As explained above, according to this invention, by fixing the backing plate to the emergency stop frame with screws and bringing this backing plate into contact with the inner end surface of one of the left and right guide rails, the guide rail and the emergency stop frame can be Set the left and right positions accurately, operate the emergency stop device in this state, and fix the emergency stop frame to the guide rail.
After that, the backing plate is removed and the car is assembled using the emergency stop frame as a foundation. Therefore, inserting a positioning member with a groove-shaped cross section into the gap between the left and right guide rails and the emergency stop frame will result in the guide rail being too thick. Because the gaps are uneven, it is difficult to set the position of the emergency stop frame accurately, and there is a risk that the positioning member may come off or come loose while fixing the emergency stop frame to the guide rail with the emergency stop device. Unlike positioning components that are expensive, this design has good workability by requiring only one backing plate to be attached and removed with a screw, and allows for accurate positioning of the emergency stop frame, eliminating the need for the backing plate to be unintentionally moved during work. The effect is that it does not come off and the backing plate has a simple structure and is inexpensive.
